摘要： A closed-case impact sprinkler unit having an outer case and an internally positioned riser sleeve that is upwardly extendable into a pop-up position. The riser sleeve may be formed with an external surface that is complimentary to the internal surface of the outer case to prevent the introduction of debris into the interior region of the outer case when the riser sleeve is in a pop-up position. The sprinkler unit may further include a closed-case turret assembly rotatably mounted on the riser sleeve that includes a fluid outlet and a compact impact sprinkler arm. The sprinkler unit may include a dual-stage riser spring assembly to delay deployment of the impact sprinkler arm having a first riser spring that is compressed when a fluid enters the interior region of the outer casing to move the riser sleeve in a relatively upward direction, and a second riser spring that is compressed upon compression of the first riser spring to disengage a valve assembly that permits the flow of fluid and activation of the sprinkler. The invention further provides a trip assembly that includes an elongated actuator opening and a trip pin pivotally mounted within the actuator opening to allow lateral movement of the trip pin which initiates a delayed reversal of the trip assembly upon contact with a trip to provide an extended sprinkling range.
摘要翻译：一种封闭式冲击式喷淋装置，其具有向外延伸到弹出位置的外壳和内部定位的提升套筒。提升套筒可以形成有与外壳的内表面互补的外表面，以防止在提升套筒处于弹出位置时将碎屑引入外壳的内部区域。喷洒单元还可以包括可旋转地安装在提升管套上的封闭式转台组件，其包括流体出口和紧凑的冲击式喷洒臂。喷洒器单元可以包括双级提升弹簧组件，以延迟具有第一提升管弹簧的冲击喷洒臂的展开，当第一提升弹簧在流体进入外壳的内部区域时被压缩，以使提升管在相对向上的方向移动，以及第二提升弹簧，其在第一提升管弹簧的压缩时被压缩以脱离允许流体流动和喷洒器的启动的阀组件。本发明还提供了一种跳闸组件，其包括细长的致动器开口和枢转地安装在致动器开口内的跳闸销，以允许跳闸销的横向移动，其在与行程接触时启动跳闸组件的延迟反向以提供延长的喷洒范围。

摘要： A dirt-resistant bearing system for a sprinkler unit with a rotatable turret having a central shaft extending into a support channel formed within an inner housing. The central shaft may be formed with a relatively upper shaft portion and a relatively lower shaft portion, and the support channel may be formed with an upper channel region and a lower channel region. A first bearing and sealing assembly may be fitted substantially around an outer perimeter of the upper shaft portion and in communication with the upper channel region, and a second bearing and sealing assembly may be fitted substantially around an outer perimeter of the lower shaft portion and in communication with the lower channel region. Another aspect of the invention provides a sprinkler head with a fitted serrated seal assembly. The fitted seal assembly may include an outer case having an interior region, and a pop-up sprinkler head turret mounted on a riser sleeve slidably mounted within the interior region of the outer case. The turret may be formed with an elongated central shaft for the passage of water. A water filter may be also provided within the riser sleeve having a valve stem for communication with a lower end portion of the central shaft. The communicating surfaces of the lower end portion of the central shaft and the valve stem of the water filter may be formed with complementary serrated surfaces.
